摘要/Abstract

摘要： 粒子图像测速（PIV）是一种非接触式的流场测试技术，被广泛应用于液体或气体的流场测定。阐述了PIV技术的基本原理，对PIV技术在测量无风墙通风轴流风机附近的流场的应用进行了实验研究。实验分别测试了模型巷道进风口面积为0.04、0.03、0.02 和0.01 m2 4种情况下无风墙通风轴流风机附近的流场。实验表明：运用PIV技术测试无风墙通风的流场是合理可行的，实验能够较为精确地测试出轴流风机附近的流场；轴流风机出风口处的上方风流流场中出现了明显的涡流；随着模型巷道进风口面积的减小，轴流风机的出风口与进风口间产生了循环风流，且循环风流的风量与模型巷道的进风口面积的大小成负相关的关系。

Abstract: The particle image velocimetry（PIV）is a non-intrusive technique to measure the flow field，which is widely used in the single-phase liquid flow as well as in the air flow.The basic principle of PIV is described，and experimental study on the application of PIV in measuring the flow field near the axial fan of the ventilation without wall is carried out.The experiment tested the flow field near the axial fan of the ventilation without wall when the inlet area of the model tunnel is 0.04 m2，0.03 m2，0.02 m2 and 0.01 m2.The result shows：it is reasonable and feasible to measure the flow field of the ventilation without wall by using PIV，which can get the flow field near the axial fan accurately；There is an obvious vortex in the air flow field above the outlet of the axial fan.The circulating air flow is generated between the outlet and the inlet of the axial fan with decreasing the inlet area of the model tunnel，and the air volume of circulating air and the inlet area of the model tunnel are negatively correlated.
